New Grower LST fail. And nute question?

[wightwitch]

Well we've stretched and now have Xmas trees! [emoji16] I clearly failed with the lst! I'll give it another bash next time round.
Planning to change to bloom nutes soon. Do I carry on cal mag through flowering? Pk will be throughout so I thought they'll need cal mag alongside? And when we change do I start with booster and continue through as well? Alongside terra Flores?
I've burnt tips already so am worried about huge amounts of nutes at once? Thanks for any thoughts. I'll be glad to get to the end with this. Gonna pop some more seeds in last month and hopefully be more organized. LST earlier see if I can get it right. [emoji3] thanks for any advice?

I am new as well but will speak on what I've done. I am not using the same nutes as you so won't comment on that. I use cal mag from day 10 to finish. If your using LED you will need a heavy dose.

It's not to late to lst. The flatter and more even your canopy is the lower you can keep your lights and the more buds get higher intensities. This is the best thing you can do for your plants hands down. If they are to stiff just go easy and try to lower the taller branches. Take measurements at the light to tallest bud and do it again when your done. You will be very surprised on what you record.

The inverse square law and lighting is something worth looking into. When I take par readings it's almost baffling. 12" for example may be around 800 umoles. 24" is not half of 800 it's more like 200-300. So the top of your plants may be getting 800 for example but the lowers look much farther away than 24" so you are probably not getting much light down low at all. The tallest bud is far from the entire yield and it's best to treat the whole plant equally.

As far as nutrients go I do believe adding in higher amounts of PK will lock out calcium. I'm struggling with this myself as every time I hit flower I get major cal deficiencies. I have tried optic foliar and also tried adding in calmag with the optic foliar and seen very little change. Currently I'm spraying with cal/carb in hopes of fixing the issue and giving the plants what they need while going heavier with the pk.

The above is the right place for general questions and you might get a better response there. This is the Intro section. Have you done one my friend ?

cheers, eP.

Thanks for the info. I hear you. I looked fearfully to work out where to bend stem... and I've come up with a cunning plan. I'm gonna add a couple of lights and arrange tallest girls together shortest together etc... which will lessen to amount of bending I need to do. I've been really surprised at how different they all are. Tall short fast slow... determined next run to get the LST cracked. Less plants will help in that I think.

Hi thanks for reply. I'll look up symptoms and check on that. So keep up the cal mag through flower?
